2,973 candles were made in remembrance for all those we lost. A vigil gives us a chance to pray for a loved one, but more practically to show they are never alone. Please join us to light a candle, say a prayer and remember.

Team Red White and Blue Moving Tribute

8:30 a.m.

No matter where you’re going to be on Sunday, please join Team Red, White & Blue and make a “moving tribute” to honor those lost on 9/11, the servicemen and women who have been killed or wounded since 9/11 — and all their families. By committing to walk, run, bike or hike on Sept. 11, we are carving out time on this 10th anniversary to reflect upon the tremendous sacrifice so many Americans have made. Team RWB has people from all over the world, including soldiers deployed to Afghanistan, who are joining us in our mission to honor and remember. We encourage you to spread the word and make this tribute in groups, and where possible to meet at 8:30 a.m. to hold a moment of silence at 8:46 a.m. — when the North Tower was first attacked.

Ten years to the day that two hijacked planes crashed into the twin towers of the World Trade Center in New York City, Penn Museum marks the solemn occasion with two special programs Sept. 11, and one Oct. 12 — and a powerful display, Excavating Ground Zero: Fragments from 9/11, on view through Nov. 6, 2011. The program and the display offer visitors a timely opportunity to remember — and reflect anew. On Sunday, Sept. 11, 2011, Penn Museum offers pay-what-you-want admission.
